I detailed this earlier in the thread, but that is generally correct. The first version is dependent upon your physical mobile phone to "do the deed" relative to phone calls; the latter version has a cellular radio within it that has it's own cellular credentials with your carrier of choice to support calls. With Apple, someone calling would still call only your mobile phone's number and both your phone, wherever it might be, and your watch would ring. For outgoing calls, only the phone's number would show for CID. I suspect that the Android version would work the same because it makes the most sense. The cost to register the watch with the carrier is much less than a normal "line" of service in most cases.
